## ⚡ Weekly Recap: $387M Crypto Hack, Citrix Exploits, AI Agents Go Off-Script, and More Threats
A domain used as harmless placeholder text showed up in roughly 1,700 repositories. Then somebody registered it and started serving malicious lures. That is the kind of week this was: forgotten assumptions turning into live attack surface.
Elsewhere, weak service accounts, old bugs, exposed systems, phishing kits, and strangely easy exploit paths kept doing useful work for attackers. Nothing exotic. Mostly things nobody expected to matter anymore.
Here’s the full recap of what mattered this week.
